This invention, generally stated, relates to a building construction andhas more particular relation to flooring made up of precast slabs whichmay be either of waterproof- I ing material perse or provided with `acoatf ing or layer of waterproofing materia-l..

One object of the present invention is to provide a simple, eicient, andcomparatively inexpensive arrangement of parts for the rapid assemblingby unskilled labor of liooring possessed of Waterproofingcharacteristics.

A further object of the present invention is to provide an arrangementand construction of parts of the character stated in which adjacentVpre-cast slabs are tied or coupled together by means of reinforcingrods or wires longitudinally considered.

A further object of the present invention is to provide a pre-castfslabof the character stated the under surface of which is provided withspaced, pendant, integral flanges which flanges have embedded thereinlongitudinally extended reinforcing rods the terminals of which rodsextend beyond the slab ends for clinching with reinforcing rods ofadjacent slabs.

A further object of the present invention isto providea structure of thecharacter stated in which there is provided intermediate adjacent slabsa vertically arranged apertured web for interlocking adjacent slab endswith respect to floor beams constituting part of the floor structure.

A still further object of the present invention resides in the providingof general details of structure and arrangement of parts as willhereinafter more fully appear.

The invention consists ofthe novel construction hereinafter more fullydescribed and finally claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description 45 taken inconnection with the accompanying drawing forming part hereof,` and inwhich: Fig. 1 is a view, principally in longitudinal section of flooringembodying the invention; Fig. 2 is a fragmentary view in plan of thepart shown in Fg- 1S Fig. 3 is a fragmentary view of the underl vside ofthe part shown in Fig. 2;

Fig. 4 isan end view, partly in section, of Fig. 2; y Fig. V5 is a viewin side elevation of Fig. 3;

Fig. 6 is a fragmentarypview illustrating the manner of tying togetherthe reinforcing rods shown in Fig. 1;

Fig. 7 is a fragmentary view in elevation hereinafter referred to;` y

Fig. 8 is a view in section taken upon the line88 of Fig. 7; and y Fig.9 is a view in perspective of a tie piece hereinafter referred to. f

For the purpose of illustrating my invention I'have shown intheaccompanying draw v ing one form thereof which is at present vpreferred by me, since thel same has been found in practice togivesatisfactory and reliable results, although it isto be understoody thatthe various instrumentalities of which my invention consists can bevariouslyarranged and organized and that my invention is not limited tothe precise arrangement and organization of the instrumentalities ashere- 75 in shown and described. v

Referring to the drawing inV detail, the reference numeral 10 designatesspaced floor members as I-beams for supporting the novel lpre-cast slabs11 embodying the invention. 80 These slabs 11 maybe made of anysuitablematerial, preferably possessingwaterproofing characteristics. Each slab11 is provided uponits under face and formed integral therewith withpendant, longitudinally eX- tended ribs 12, as best seen in Figs. 3, L1,and 5. Embedded in each rib 12 is a longitudinally extended member 13,as a rod or wire. VThe ribs 12, as before stated, are arranged in spacedrelation and the ends thereof are bevelled ,as at 14. Each reinforcingmember 13 throughout the maj or portion of its extent parallels thebottom of a slab as clearly shown in Fig.` 1. Each reinforcing member atits ends is vdeflected upwardly atan angle Y15, 95

see l, and thereafter is extended outwardly as at 16 in a horizontalmannerto parallel the major :portion-of the eXtentof Y said reinforcingVmember, fand is thereafter extended upwardly in parallelism asiat 17, as100 best seen in Fig. 1. The object in having the ends of thereinforcing member extended as at 17 is that of providing means wherebya tie wire 18 may be adjusted with respect to the up-turned ends of thereinforcing member to couple the precast slabs together, as best seen inFig. 6.

rllhe central rib of each slab has embedded therein a verticallyextended plate 19 apertured as shown in Fig. 5 to lighten construction.This plate extends from the central rib upwardly and terminates short ofthe top of a slab as shown in Fig. 4. Both the upper and lower portionsof said plate are flanged as at 20. y

Adjacent the abutting portions of the floor slabs there is provided adevice as best yseen* in Fig. 9 which is made of wire and comprises .across piece .1 and appair of parallel prongs 22. In practice theseprongs 22 are introduced through one end 'of aV floor slab, as best seenin Fig. l, and the ends of the prongs 22 are turned over as at 23beneath the flanges of a. iloor beam 10. In the connection it is to benoted that the cross bar 2l of this device, as best seen in Fig. 8, isembedded in the slab material. The yabove construction anchors the floorslab with respectto the floor beams l0. In practice a cementitiousflooring material 2i is applied over the flooring slabs il.

In order to accommodate the cross bars 21 the slabs lll are notched asat 25.

The slabs 1l in order kto provide lateral interconnection are notched asat 26 and provided with a rib 27 opposite to the notch 26 whereby theslabs may be interlocked one with respect to another. y

What is claimed is:

l. In a building construction of the character stated, flanged floorbeams, pre-cast slabs the ends of which are cuty away to lit over theupper flanges of and be supported by said beams, said slabs havingembedded therein longitudinally extended reinforcing rods, the terminalsof which rods extend first through the slab ends at an upwardlyextending angle entirely free of the beam flange and thereafter areextended vertically beyond a slab end, means for tying together thevertically extended portions of said reinforcing rods of companionslabs, a. cementitious fill .covering said slabs including said coupledtogether ends of said reinforcing rods, each slab beingprovidedlaterally considered with a notched portion, and a tie-pieceaccommodated in said notched portions the terminals of said tie-piecesbeing clamped beneath the undersides of the beam flanges.

2. In a building construction of the character stated, flanged floorbeams, pre-cast slabs the ends of which are cut away to fit over theupper flanges of and be supported by said beams, said slabs being`provided with `:pendant spaced -langes each flange having i,s91,51's

embedded therein longitudinally extended reinforcing rods, the terminalsof which rods extend first through the slab ends at an upwardlyextending angle entirely free of the beam flange and thereafter areextended vertically beyond a slab end, means for tying together thevertically extended portions of said reinforcing rods of companionslabs, a cementitious fill covering said slabs including said coupledtogether ends of said reinforcing rods, and an apertured and flangedreinforcing plate embedded in each of said slabs and extendedinto anintermediate of said flanges. f

3. In a building construction of the character stated, flanged floorbeams, pre-cast slabs the vends of which Iare cut away to 'it over theupper flanges 'of and be supported by said beams, said slabs beingprovided with pendant yspaced flanges each flange having embeddedtherein longitudinally extended reinforcing rods, the terminals of whichrods extend first through the slabfends at an'upwardly extending Vangleventirely free of the beam flange-and thereafter are extended verticallybeyond a slab end, means for tying together the vertically extendedportions of said reinforcing rods of companion slabs, a cementitiousfill covering said slabs including said coupled together ends of saidreinforcing rods, andan aper-tured and flanged reinforcing plateembedded in each of said slabs and extended into an intermediate of saidflanges,the said reinforcing rods following the general vcontour of saidreinforcing plate. e

4. In a building construction of the character stated, met-allie floorsupports, pre-cast slabs the ends of which are cut away toit over theV-up'per flanges of and be supported by said beams, said slabs beingprovided with pendant spaced flanges each flange having embedded thereinlongitudinally extended reinforcing rods, the terminals of which rodsextend first thru the slab ends at an upwardly extending angle entirelyfree of the beam flange and thereafter areextended vertically beyond aslab end, means for tying together the vertically extended portions ofsaid reinforcing rods of companion slabs, a ce- '115 mentitious fillcovering said slabs including said coupled together ends -of saidreinforcing rods, and anaper-tured and flanged reinforcing plateembedded in each of said slabs and extended into lan intermediate ofvsaid flanges.
